“I'm stupid," Leo mumbled. "Pi would expand outward, because it's infinite." He reversed the order of the numbers, starting in the center and working toward the edge. When he aligned the last ring, something inside the sphere clicked. The door swung open. Leo beamed at his friends. "That, good people, is how we do things in Leo World. Come on in!" "I hate Leo World," Frank muttered. Hazel laughed.”

“Leo,” Hazel gasped, “I can’t—my arms—”“Hazel,” he said. “Do you trust me?”“No!”“Me neither,” Leo admitted.”

“Frank gave Leo a confused smile- like he couldn't decide whether to gloat or to thank Leo for being a doofus- but he cheerfully let Hazel drag him along.”

“We started this together, Leo. Seems only right you come along. You find us a ride, you're in.""Yes!" Leo pumped his fist.* * * * *Jason gazed up at the dragon and shook his head in amazement. "Leo, what have you done?""Found a ride!" Leo beamed. "You said I could go on the quest if I got you a ride. Well, I got you a class-A metallic flying bad boy! Festus can take us anywhere!”

“Hazel!” he yelled. “That box! Open it!”She hesitated, then saw the box he meant. Te label read WARNING. DO NOT OPEN. “Open it!” Leo yelled again.”

“Leo choked. "Your mom is a rainbow goddess?""Got a problem with that?" Butch said."No, no," Leo said. "Rainbows, very macho.""Butch is our best equestrian," Annabeth said. "He gets along great with the pegasi.""Rainbows, ponies," Leo muttered."I'm gonna toss you off this chariot," Butch warned.”

“They would find this House of Hades. They'd take the Doors of Death. And by the gods, if Leo had to design a grabber arm long enough to snatch Percy and Annabeth out of Tartarus, then that's what he would do. Nemesis wanted him to wreak vengeance on Gaea? Leo would be happy to oblige. He was going to make Gaea sorry she had ever messed with Leo Valdez. "Yeah." He took one last look at the cityscape of Rome, turning bloodred in the sunset. "Festus, raise the sails. We've got some friends to save.”
